The team keyvalue appears to have no effect on this entity.
- The keyvalue exists though. It might be a bug. --Baliame 07:23, 10 Nov 2007 (PST)
- I have tested the TeamNum keyvalue. Neither team can build in the nobuild as long as it's active, regardless of the keyvalue. Is there any change that we can get his implemented, Valve? It would be really nice to disallow a team from camping a spawn with sentries, and still allow the spawning team to build their teleporters. --Hovis 20:45, 23 January 2009 (UTC)
I'm not sure if my wording is as clear as I wanted it, so I added an example map to demonstrate what I'm talking about.--Brandished 23:36, 22 Jun 2008 (PDT)
